Marketing moves to where consumers convert, so political ads are moving in droves to Facebook. When I wrote “How Trump Won” in January 2017, the Trump campaign’s digital director credited Facebook as the fundraising powerhouse. Last week, The New York Times’ headline was “How Trump Is Outspending Every 2020 Democrat on Facebook.”

What’s the best way to attract more than 600 people to an event? A campaign that draws the attendee in and then wows them. In this case, Visit Philadelphia, the region’s official tourism marketing agency, did just that.
